1998 saw several new ventures promoting online distance learning both at the college and graduate level, but also faculty members in large numbers began questioning whether the computer screen was an adequate replacement for the classroom.

(A) 1998 saw several new ventures promoting online distance learning both at the college and graduate level, but also faculty members in large numbers began

(B) In 1998 several new ventures were promoting online distance learning for both college-and for graduate-level courses, but it was also a year for a large number of faculty members who began

(C) With several new ventures promoting online distance learning both for college and graduate courses in 1998, it was also a year when a large number of faculty members had begun

(D) Although 1998 saw several new ventures promoting online distance learning for both college- and graduate-level courses, it was also a year when a large number of faculty members began(D)

(E) Several new ventures were promoting online distance learning in 1998, at both the college level as well as the graduate, but it was also a year for faculty members to begin in large numbers

这里的正确答案中出现a year when，when为关系副词引导定语从句

但是，白勇有云：

the year + that; a year when

因为用the，而前面又没有提到过year，所以只能在定语从句里面对之加以说明，所以用that

而用a，说明只是第一次提到，定语从句也不对其进行说明，其在定语从句里面也只是做状语，所以用when.

用when也可以起到说明作用啊

（2）1932 is the year when I was born.

说明1932是我出生的那一年

对的

我差点用这个规则排掉了正确选项

sigh......看来实战一定要小心

1998 saw several new ventures promoting online distance learning both at the college and graduate level, but also faculty members in large numbers began questioning whether the computer screen was an adequate replacement for the classroom.
                

(C) With several new ventures promoting online distance learning both for college and graduate courses in 1998, it was also a year when a large number of faculty members had begun

请问：如果将后面的BOTH AND 改对 HAD BEGUN 改成BEGAN  是不是就对了 WITH 独立主格做状语  同时发生

可是解释上说，WITH 改了逻辑关系 将并列分句改成了主从成分  啥意思？谢谢！
